don, as you may know, my engine was built from the ground up to be what it is. it has all forged internals and slightly lower than stock compression as well as different head gaskets and head studs. essentially a stroker built to run with forced induction. i'm sure thats a good part of why i have very little issue with it and i would guess that it should stay the same if i chose to run it in a more competitive environment than drivers ed. it would be interesting to see what a stock internal motor with boost would do over time on the track.

"No such thing as a free lunch?" I guess I know that, by now. I am sure the dependability of your car's power, and the one mentioned in the previous post as the "Blower Motor car" in it's latest form ,is a result of building each of it's engines stronger than the one before, until it stops blowing up...Development time and money, in other words. My original question was aimed at finding out what routes had been tried, and with what success, on forced induction motors...ie, dry sump, different oiling for the 2/6, coolers, etc..all the expected stuff that has shown up as weak spots in NA race motors.. We know, at least we should know, that if you hop up a motor, it's gonna blow if you don't "beef-up" a lot of the weak stuff, too.
I suppose another way to consider it would be...A street car, no matter how high performance, is only engineered to endure under street conditions or whatever the engineers deem as it's possible use...You take one and "boost" it's power, then drive the snot out of it....It will be likely to exceed it's limits and "grenade"..So, we look around and we try to find out what fails on other similar motors, used in similar fashion, then spend enough and build it stout enough to live a reasonable amount of time..The amount of time any motor can live is pretty dependent of what kind of power you ask it to put out and what kind of use you put that power to...
Like the ~2000 hp funny car motors that last maybe 20 seconds between builds..or the 40 hp VW that lasts 40 years...
